INFLATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 559,848, dated May 12, 1896.

Application filed May 25, 1895. Serial No. 550,673. (No model.)

To @ZZ whom t nur/y con/cern:

Be it known that I, HENRY 'LAWRENCE GUL- LINE, of the city of Victoria, in the Province of Brit-ish Columbia, Canada, have invented certain new and useful Improvements in Inilating Devices; and I do hereby declare that the follouingis af ull, clear, and exact description of the same.

This invention relates to the inflating devices for use in connection with bicycle-tires, air-cushions, and other inflated articles, and has for its object to improve the construction of the air-nipple thereof, which is carried by the article to be inflated, and to secure a better and more ready connection of the air-supplyin parts With such nipple when required, as Well as the construction of such parts, so that when in place the valve of the nipple can be opened, air pumped in, and the valve closed without disconnecting the air-supply from the nipple. IIcretofore the air-nipples have been constructed of numerous detachable parts easily disconnected and liable to become lost and there has been practically no effeet-ive guards aga-in st inoperati veness caused by the clogging and sticking of the working parts through the entry of dirt, soapstone, &c.

My improvcm ents avoid all the above-n oted objections, securing a compact nipple, all the parts of which are safely held against any possibility of accidental detachment, and further provide eifective safeguards to prevent the entry of any substance detrimental to the working of the nipple.

The improvements consist, first, in placing the valve or valves and other parts Within the casin g orbody of the nipple and then brazing or turning in the ends of such body, so as to prevent any accidental displacement or loss of such parts; secondly, in the introduction of dust-guards at each end of the nipple; thirdly, .in the special. construction of the auxiliary or check valve located at the inner end of the nipple, and, fourthly, in the special form of a portion of the body of the nipple to pre vent any turning or twisting thereof in the material in which it is set, another feature being the combination, Wi th the air-supply tube, of a key for opening and closing the valve of the nipple, the combination allowing the valve to be operated While the supply-pi pe is connected with the nipple.

Having thus referred to the object and pri nciple of my invention, I Will now describe what I consider to be the most practical embodiment thereof in an inflating device to be used for the inflation of bicycle-tires, reference being had to the annexed drawings, forming a part of such description, in which like symbols indicate corresponding parts and Wherein- Figure l is a longitudinal vertical section of a portion of a bicycle-tire with my invention applied thereto; Fig. 2, an enlarged transverse vertical section of the nipple, taken on line 2 2, Fig. l; Fig. 3, a transverse horizontal section of saine on line 3 3, Fig. l; Fig. 4, an end vieiv of nipple; and Fig. 5, a perspective view of an air-supplying device with my improved key attached to the supply-tube thereof, such tube being partly broken away.

a is a portion of the usual metal or Wooden rim of a bicycle-Wheel, and a' thehollovv rubber tire thereof.

The body l) of the air-nipple is of cylindrical form from the top to a point about midway of its length, below which its entire exterior surface is enlarged somewhat, as at b', and of a form other than cireular-elliptical, for instancedthe upper portion of such enlarged and differently-shaped portion fitting a corresponding opening a2 in the rim u., so as to prevent any turning or twisting of the nipple in the material in. which it is set when the valve of the nipple is being operated. ln some cases it might be found desirable to form lugs with eyes through them, instead of the enh rgeinent or elliptical form, to allow of the nipple being tied in place by a Wire fastening. The upper portion of the nipple is bored and screw-threaded to receive the valve proper, c, screw-threaded to Work therein, the inner end or head portion of such valve being of conical form and adapted to Work upon a corresponding seat c', preferably faced with soft metal d. The stem portion of the valve is slotted longitudinally, as at c2, from its outer end inward to the head, which is of slightly less diameter than the stem, in order to provide an air-space c between it and the body. A central air-passage g leads from the air-space c to the inner end of the nipple, Where it preferably terminates in an enlargement or chamber g', in which I prefer to lo- ICO cate an auxiliary or check valve made of metal and having a conical head h, a stem 7L', and a slit 72,2 in one side of such head, the stem projecting into the passage g and the valve-head bearing upon the lower edge thereof when lifted by back pressure of the air in the tire. The slit 71,2, while interfering to a limited extent with the checking function of the valve, yet prevents any serions difficulty that might be caused by the sticking of the valve in its closed position, and so preventing` entry of air, when desired, and this is much more likely to occur when such valve is in the form of a rubber disk. Furthermore, such rubber disks are always more or less liable to harden, and thus become defective in operation.,

As safeguards for the prevention of the entry of dirt, dust, soapstone, or any other substance detrimental to the workin g of the parts in the nipple I prefer to arrange in the slit e2 of the valve proper a movable dustguard in the form of a plate 7i'. about half the length of the slit and of such a thickness as to freely slide in saine and not interfere with the passage of air therethrough and insertion of the operating-key, as hereinafter described, such plate being supported or pressed nor* mall y outward with its end ii ush with the end of the nipple by means of coiled spring k beneath it and retained in place by a pin it?, passing transversely through the valve-stem, and a longitudinal slot 7e3 in such plate. At the opposite end of the nipple the second guard, inthe form of a disk m, of woven wire of very line mesh, is placed across the month of the chamber y', in which the checlevalve is located and held in place by the brazin g er turning inward, as at n, of the thinned end of the body, the movement of the valve proper being .limited in the same manner by the brazing or turning inward of the opposite thinned end of the body.

From the foregoing it will be seen that a compact and reliable form of nipple is secured without any chance of detachment and loss of parts or of such parts becominginoperative in any way.

The nipple is connected with the rubber tire in any usual way, although I prefer to first cement the lower portion of the body, insert it in the customary rubbercollar 0, and then bind it tightly by any suitable wire or other binding, (indicated at 0,) after which the collar o is cemented to the tire.

To inflate the tire, it is customary to force air through the nipple by means of an atomizer or air-pumping appliance of some kind, and in order to allow of the valve c being opened and closed while the conducting-tube leading from the atomizer to the nipple is connected with the latter I insert in the end of such tube a metal key-piece having a hollow cylindrical body p, with a projecting tongue p adapted to enter the slit c2 of the valve and turn same, suitable ears or wings q being formed on the body to afford a convenient finger-hold. An additional length of flexible tubing-r has one end secured to the outerend of the body p and ext-ends freely for the length of the tongue p', so that when the latter is inserted in the slit of the valve the tubing r is fitted over the body, as shown in dotted lines in Fig. 2, and its :flexibility allows the rotation of the key-piece a halt'- turn in either direction, which is sufficient to secure the Opening and closing of the valve.
